The "free end .of .the bnderfifstrip is connected by stitching or `a suitable detachable connection, rsuch as the hingetype ofilacing used Ain power beltsto one end of .a cover strip.

"The assemblyiillustrated l comprisesa "binder strip "-Ii having one edge permanently secured .to the 'ironer `roll l H,"a 'cover :strip l2 connected to "th'e'iree end ofthe'binder strip by ahinge connection, andapadding'l 3 `wrapped about the roll with thebinder and"`cl0ver strips. The binder "strip isirn'adebf a thin`corrosion- "resistant'shee't metaLsuch las Monel metal, and thecover lstrip is preferably madeof asbestos fabric impregnated with 'a phenolic or similar resin. Thepadding 113 may be of cotton or partly of i'asbestos "and"partly 'o'f cotton.

Theend of "the'binderfstrip 10, `Whichis to oe "secured Ito the roll, isprelirninaril-y folded back upon'itself, as indicated "at `Illa, (Fig. 2) and a plurality-of openingsA lfdiare'th'en formed through *the double'thicknessof the stripinarow and at relatively close 'spacingsl `In orderfto 4secure the -`folded end of 'thi-:istrip to 'the roll, the roll is drilled along alengthwise line and `on spacings vcorresponding tothose of openings it. The reversely folded endof 4the strip'is then applied to the *roll with the openings -l4 inthe strip in u'egistrylwith thedrillholes'an'd rivets f5 of a size "to have a ktight ft in "the `drill Vholes are "then driven `through the openings and into the -holes to "secure the foldedend of the Vstrip permanently to the roll.

At'thefreeend of thebinderstrip lil, which is "to -form ia :parteci the hinge connection, a

`jplurality-l'of sjquarefopenings IS `are 4made in the strip 'in "a transverse -row and the strip is then ```fo`lded`bacl-i Vupon itself -on Va line lengthwise of 1the `openings through their centers. Areinforcementwhich may I'take theform of a wire Vl of 'stainless steel, is insertedv in the lfold and `the two plies of metal inwardly A'from `the lin-e of fold- Eing *are 'then secured together "in 'any l'suitable "manner, `fas "by "spot zfielding as indicated -at I8.

The cover strip l2 is of relatively weak construction and, in order to strengthen it at the hinge connection, the strip is doubled back upon itself, as indicated at I9, and a reinforcing wire 20 is inserted in the fold. A sheet of corrosionresistant metal 2 l, which is equal in width to the cover strip and is preferably Monel metal, is provided with plurality of openings in a transverse row and separated by narrow tongues 22, and the sheets then folded on a transverse line through the middle of the tongues. The free edges of sheet are then applied to opposite faces of the reversely folded edge of the cover strip and secured in position by rivets 23, which pass through the two plies of the metal and through the two plies of the cover strip inwardly from the reinforcement. If preferred, two sheets of metal formed with tonges projecting from one edge may be secured, as described, against opposite faces of the reversely folded edge of the cover strip, the tongues lying face to face. The double thickness tongues 22 formed as described are of a size and spacing corresponding to that of the openings I6 in the binder strip and are relatively flexible. In order to make the connection between the strips, the tongues are bent and passed through the openings I6 and then further bent backwardly upon themselves, as shown in Fig. 3. If it is desired to detach the cover strip from the binder strip, the tongues can be readily bent sufciently to permit their removal from openings I6.

In the alternative hinge connection shown in Fig. 4, the free end of the binder strip I' is reversely folded, and spaced sections of the fold are cut away. A short length of tube 24 is then inserted in each remaining portion of the fold and the inturned edge of the strip is secured in place in any suitable way, such as by means of spot welds I8', to hold the lengths of tube in position. One edge of the cover strip l2 is reversely folded and a reinforcing wire 20 is inserted in the fold. A sheet metal member 25 is folded upon itself and its ends are applied to opposite faces of the folded portion of the cover strip and secured in place by rivets 23 passing through the plies of member 25 of the strip inwardly from the wire 20. The member V25 is of such size and so disposed that its folded edge lies outwardly beyond the end of the cover strip and the folded edge of the member is cut away to form spaced recesses, in which may be inserted the spaced sections of the folded edge of the binder strip containing the lengths of tubing 2G. Between the recesses, lengths of tube 26 are inserted in the fold of member 25 and the plies of the member are secured face to face in any suitable way to hold the tubing in place. In order to make the connection between the binder and cover strips provided with the hinge illustrated in Fig. 4, the edges of the two strips are assembled with the inserted tubes in alignment, and a long pin 21 is then passed through the aligned tubes.

After the binder strip has been permanently attached to the roll and the cover strip connected to the free end of the binder strip by the hinge connection, as described, the strips and padding I3 are wound about the roll to complete the assembly. The padding employed may be relatively thin and of such length as to extend twice about the roll or the padding may be heavier and extend only once about the roll. With eitherV arrangement, the padding is applied in such manner that a portion of the padding overlies the hinge connection and thus prevents the connection from indenting the material being ircned. Y

In Fig. 5, there is illustrated a long thin padding applied to the roll and, when such a padding is employed, the binder strip 28 is preferably of such length as to extend through about 3A of the circumference of the roll. The paddling |3a is applied with its inner end beneath the binder strip and lying close to the connection of the strip to the roll. The padding extends around the roll beneath the hinge connection and thence passes over the connection of the binder strip to the roll. The second convolution of the padding overlies the binder strip and a portion of the cover strip 12a and the outer end of the padding terminates close to the inner end thereof and without overlap. The cover strip used with the assembly shown in Fig. 5 is of sufficient length to extend twice around the roll plus a substantial distance beyond the outer end of the padding, as for example, through about 1/4 the circumference of the roll.

In the construction shown in Fig. 6, the padding I 3b is about twice the thickness of that used in the Fig. 5 construction and the binder Y strip 29 is relatively short and lies in direct contact with the roll. One end of the padding then lies beneath the cover strip just beyond the hinge connection and the padding extends through one circumference of the roll and overlies the hinge. The cover strip l2b is of sufficient length to be wrapped once about the roll plus an additional distance equal to about 1A, of the circumference of the roll. i

In the new assembly, the binder strip of corrosion-resistant metal permanently affixed to the roll remains in place indenitely. The cover strip, which is of weaker material, is reinforced at the hinge connection by being folded back upon itself and about the reinforcing wire. The folded portion is then further strengthened by the riveting of the one portion of the hinge connection against opposite faces of the reversely folded edge of the cover strip. Because of the reinforcing of the cover strip at the connection, the strip is of long life and it is not likely to be torn free from the cover strip in use. Should the binder strip or padding need replacement, it is a simple operation to unwind the assembly from the roll, replace the cover strip, and rewind the parts of the assembly.
